IMPROVEMENT IN CIGAR-'MCLDS.

Specification forming partof Letters Patent No. 14%,617, dated February17, 1874; application filed October I8, 1873.

To all whom it may concern:

Be it known that I, NAPOLEON DUBRUL, of Cincinnati, in the county ofHamilton and State of Ohio, have invented an Improvement in Cigar-Molds,of which the following is a specification My invention relates to acigarmold constructed in two parts, with cavities in their opposingfaces, those in the base of the mold containin g plungers connected toone or more back strips, which, in my improvements, project below thebase, so that when placed in a press the plungers will be forced upsimultaneously, compressing the cigar-fillers upward into the cavitiesof the cap or cover of the mold, as hereinafter described. The object ofthe invention is to produce a machine which may be used with rapidityand success by unskilled hands. The plungers in their retracted positionare seated on the longitudinal bars of the base, which limit theirdownward movement and prevent their separation from the base. Theconnecting bar or bars of the plungers projecting below the base adaptany desirable number of the molds to be pressed at once by placing themone on another within the press. This facility for simultaneous pressureconstitutes a leading feature of utility in my improvement. The plungershave a limited and simultaneous movement within the base, but areinseparable therefrom, and the parts are so arranged that in theretracted condition of the plungers the strip or strips by which theyare connected project below the bottom, so as to afford means ofapplying pressure to all the followers in any number of moldssimultaneously, by the simple superposition of a number of molds oneover another in the press.

In the accompanying drawings, Figure 1 is a perspective view of the capor cover of the mold. Fig. 2 is a perspective view of the base portionthereof. Fig. 8 is a front elevation of the entire mold, partly insection. Fig. 4: is a transverse section on the line no a, Fig. 3,showin g the plungers retracted. Fig. 5 is a section in the same plane,showing the parts of the mold pressed together, and a cigar-fillerwithin the matrix. Fig. 6. is a transverse section on the line y y, Fig.3. Fig. 7 is a transverse section,illustrating a modificationhereinafter described.

The cap or cover C of the mold is formed with any desirable number ofcavities, c, corresponding in form to the half of a cigar.

Twenty constitutes a good number, a machine making twenty cigars at oncebeing :found convenient to manipulate. The base of the mold is made upof a corresponding number of divisions, D, and end pieces, D, connectedby strips A A, the said divisions and end pieces having vertical sidesso formed that the spaces at between them will correspond in horizontalarea to the shape of a cigar. Within these spaces d work plungers P,attached to a backing, B, which connects them all together, and isfitted to slide up and down between the strips A, and between offsets aa of the division pieces D, corresponding to said strips A. The plungershave concave faces of the necessary shape to impart the required form tothe cigars, and they extend to the entire width of the mold, their endsprojecting over the strips A. This limits their downward movement andtheir upward movement is restricted by the backing B, to which they areattached, and by which they are connected. In their transverse sectionthe plungers P have a tapering form, as shown in Figs. 2 and 3, so as torelieve their sides of friction, except at the extreme edges, where theynecessarily fit tightly within the cavities cl. This tapering form ofthe plungers is of especial importance in my machine, owing to the depthof the mold-cavities, and the necessity for pressing back all theplungers simultaneously with the fin gers. The said form is also usefulin effectually preventing the sticking of the plungersin the event oftheir becoming swelled by moisture. Dowels E are provided on the underside of the cap, fitting corresponding holes 6 in the base, to insurethe proper relative adjustment of the parts. i

From an inspection of Figs. 2 and 4 of the drawings, it will be seenthat when the plungers are down the backing B, to which they areattached, projects below the bottom of the strips A A. The cavities (lin the base or body-of the mold are now ready for the reception of thetobacco of which the fillers are to be formed. The material being placedin said cavities in proper quantities, the cap is placed on the mold,its surface fitting closely on. that of the base, so as to formtightjoints around the mold-cavities. The molds are then placed, anumber together, in a press, and the backing B, carrying the planners,is forced up into the position shown in Figs. 3, 5, and G, bringing thestrips A A flush with the backing B on the bed of the press or upon themold below it, so that theparts of the mold are held firmly while thefillers are pressed to the required shape.

The molds are left in the press from two to six or eight hours, orsultieiently long for the fillers to become set to the proper form. Theyare then taken out, and on taking off the cap the fillers are foundprojecting out of the cavities for one-halt their thickness, so thatthey are removed with perfect facility:

The operator, then, placinglhis fingers around the edges of the endpieces I), and pressing on the two end pluugers with his thumbs, readilypresses down the whole body of plungers at once, in readiness forrefilling.

As a manifest modification of my invention, I reserve the llff'lll], ifpreferred, to attach the division-pieces I) and end pieces I) to a stationary central backing, B, and the plunge-rs l to ed ge strips A,adapted to work up and down in recesses in the ends of the division andend pieces, instead of in the center, as in the present illustration.This'mo liii ration is illustrated in Fig. 7. Y

I do not claim broadl y, a mold made in three partsto'wit, a connectedseries of concaves at top, a connected series of plungers at bottom, anda connected series of surrounding boxes, within which the said plungerswork-except in g when-the same are constructed and combined in themanner herein specified.

hat I claim, and desire to secure by Letters Patent, is-

1. The series of plungers connected by one or more back strips, so thatthey maybe pressed down simultaneously, and projecting over thelongitudinal bars of the base, so as to limit their downward movement,and prevent their separation from the base, all said parts beingconstructed and combined as herein set forth.

2. The connected series of plungers, having a limited up-a1ul-down movemcut, as described,

in combination wit-h a mold-base, below which the backing of theplungers projects in the re tracted condition of the plunger-s, as andfor the purposes designated.
